| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class A shares gained 25.45% for the year ended October 31, 2024. That result compares with a 33.68% gain for the MSCI World Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-A What factors influenced results During the fund’s fiscal year, the U.S. experienced strong consumer spending, a healthy labor market and easing inflation. Overseas, however, many global economies began to stagnate toward the end of the period, with mixed results across Europe and the Asia-Pacific region. Within the portfolio, most equity sectors added to the fund’s positive returns, with holdings in information technology and industrials being particularly additive. Consumer discretionary and financial holdings also saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in Germany and the U.S. were additive to the return. Conversely, holdings in energy, consumer staples and health care sectors detracted from the broader portfolio’s return. The fund’s holdings in companies domiciled in Hong Kong posted negative overall returns. Investments in Australia and France, while still positive, were below the portfolio’s overall return. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class 529-T shares gained 25.78% for the year ended October 31, 2024. That result compares with a 33.68% gain for the MSCI World Index. What factors influenced results During the fund’s fiscal year, the U.S. experienced strong consumer spending, a healthy labor market and easing inflation. Overseas, however, many global economies began to stagnate toward the end of the period, with mixed results across Europe and the Asia-Pacific region. Within the portfolio, most equity sectors added to the fund’s positive returns, with holdings in information technology and industrials being particularly additive. Consumer discretionary and financial holdings also saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in Germany and the U.S. were additive to the return. Conversely, holdings in energy, consumer staples and health care sectors detracted from the broader portfolio’s return. The fund’s holdings in companies domiciled in Hong Kong posted negative overall returns. Investments in Australia and France, while still positive, were below the portfolio’s overall return. |

| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund’s Class R-5E shares gained 25.79% for the year ended October 31, 2024. That result compares with a 33.68% gain for the MSCI World Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/mutual-fund-returns-R5E What factors influenced results During the fund’s fiscal year, the U.S. experienced strong consumer spending, a healthy labor market and easing inflation. Overseas, however, many global economies began to stagnate toward the end of the period, with mixed results across Europe and the Asia-Pacific region. Within the portfolio, most equity sectors added to the fund’s positive returns, with holdings in information technology and industrials being particularly additive. Consumer discretionary and financial holdings also saw returns surpassing those of the overall portfolio. From a geographic perspective, shares of companies based in Germany and the U.S. were additive to the return. Conversely, holdings in energy, consumer staples and health care sectors detracted from the broader portfolio’s return. The fund’s holdings in companies domiciled in Hong Kong posted negative overall returns. Investments in Australia and France, while still positive, were below the portfolio’s overall return. |
